By the first week of November the oaks on Lemont's older streets let go all at once, and a yard can go from gold to bare in about four days. Sanchez Landscaping works that turn from both sides, mowing, trimming and cleaning up what carries a property through the end of the growing season, then plowing and shoveling once the ground goes hard underfoot. In between sits one short week where everything done all summer is finally visible at once. The rest of the year is quieter labor: even cuts, clean edges, walks kept passable whether what is lying on them is leaves or six inches of snow. Lemont and its neighboring towns, right around the calendar.
